The Science Behind Dense Hair Formulas

What’s actually inside Dense hair supplements, and why?

Dense formulas are built around named, researched actives rather than vague filler. Every ingredient is chosen for a specific role in supporting normal hair growth, follicle health or scalp balance: micronutrients like Biotin, Zinc and Iron, alongside botanicals like Pumpkin Seed and Pygeum. Here is what goes in, and the thinking behind it.

In short

• Dense uses 14+ named actives, each chosen for a specific role, not filler.
• Three groups: micronutrients (Biotin, Zinc, Iron, Selenium, Iodine, Vitamin E), botanicals (Pumpkin Seed, Green Tea, Pygeum, Nettle) and antioxidants (Resveratrol, Fo-Ti, Horsetail).
• Designed to support hair from the inside out, taken once a day with food.
• Hair responds over time: use consistently and check in at around three months.

Frequently asked questions

What ingredients are in Dense hair supplements?

Dense combines over 14 named actives across three groups: micronutrients (Biotin, Zinc, Iron, Selenium, Iodine, Vitamin E), botanicals (Pumpkin Seed Extract, Green Tea Extract, Pygeum Bark, Nettle) and antioxidants (Resveratrol, Fo-Ti Root, Horsetail Extract). Each is selected for its role in supporting normal hair growth, follicle health or scalp balance.

How do these ingredients support hair?

They work from the inside out by helping maintain the micronutrient status that normal hair growth depends on. Micronutrients like Biotin, Zinc and Iron play a role in normal hair, while the botanicals and antioxidants are included to support follicle health and scalp balance as part of a daily routine.

How long before I might notice a difference?

Hair is influenced by nutritional status over time, so Dense is designed as a long-term routine rather than a quick fix. Use it consistently for at least three months before assessing any change in hair condition. Results vary depending on individual factors.

When and how should I take it?

Take the recommended daily dose with food for best absorption. Consistency matters more than exact timing, so the easiest approach is to take it at the same point in your day, every day.

Is Dense suitable during pregnancy or breastfeeding?

The 2in1 Shampoo and Conditioner and the Salt Spray are designed to be safe during pregnancy and breastfeeding. For any supplement taken internally, check with your GP or pharmacist before starting if you are pregnant, breastfeeding or taking other medication.

What makes Dense different from other hair supplements?

Dense is a complete system with a UK pharmacy behind it (Dense Hair Experts): named, researched actives rather than vague, unnamed blends, plus topicals and microneedling devices designed to work together, and routines that are personalised to you rather than one-size-fits-all.
